Abstract

The URAGAN wide-aperture large-area multilayer muon hodoscope is developed for the NEVOD experimental complex of the Moscow Engineering Physics Institute. The hodoscope will be used to study atmospheric and heliospheric processes responsible for variations in the muon flux at the Earth’s surface. The structures of the detector and its system of data acquisition and processing are described. The data obtained during continuous sets of measurements in 2005–2006 using the first two supermodules of the setup are analyzed, and preliminary results of this analysis are discussed.
